| 摘 要： | 根据1988—1990年对湘江尾闾河槽进行实地考察所采集的河床底质和浅钻资料,及在艑山、岳阳、城陵矶三个测流断面所取得的水文、泥沙数据,从水动力条件和地质地貌及沉积相角度进行分析,发现河槽呈缓慢右移,右汊冲深,左汊淤浅,河宽逐渐缩窄的趋势。整治应以挖槽疏浚为主,浚深右汊中部河段,适当采取丁坝、潜坝、炸礁工程。引流归槽,以挖制河势,稳定航道。

| Abstract: | Within the east Dongting Lake area, Xiangjiang River Lower reach flows through Bian-shan and Yueyang into Changjiang River at Cheinglingji. Being a river during dry season, but a lake when flooded, the flow of water, silt and the boundary conditions are so complicated that the disorder and changes of the beaches gr eatly affect shipping. Both Yueyang and Cheng-lingji are not only the north gate of Hunan Province but also the water transportation pivot which links Dongting Lake and four other rivers with Changjing River. Because of its important economic status, we made an on-the-spot investigation of the area from 1988 to 1990. Based on the landforms, deposit face water power and the original data of hydrology and silt from the flow sections at Bianshan, Yueyang and Chenglin-gji, found that the evolution law ofthe river-bed--the river-bed has been moving gradually to the right; with the right branchgetting deeper, the left branch is getting silted and shallower, and the river itself is getting narrower. In order to control the lie of the river and have a stable waterway, we suggest that the middle part of the right branch is dredged, mainly through the way of digging, while spur dike, underwater dike and reef explosion can be applied if necessary. |
